I want to refresh all windows & panes in a Tmux session. Stumped. (Followup.)

refresh_Tmux_windows_2

In essence I want a shell script menu option to refresh Tmux windows & panes.

(There is no user tmux.conf file - I use Tmuxinator to setup Tmux {it's easier} - thus it's not going to be as easy as this Linux noob thinks!)

I have 3 files (none yet in a public repo):
1.  ~/Documents/ayadn_run.sh   - calls up a Tmuxinator file,
2.  ~/.tmuxinator/ayadn.yml    - which starts a Tmux session and in turn calls up
3.  ~/Documents/ayadn_shell.sh - the shell script menu running inside the Tmux session.

ayadn_shell.sh:
  Menu option 8 should export REFRESH=1 then kill the Tmux session, thus returning to ayadn_run.
  Menu option 0 should export REFRESH=0 then kill the Tmux server, thus returning to ayadn_run.

ayadn_run.sh:
  With REFRESH=1 variable RUNAYADN should let the while..do re-run 'mux ayadn' thus starting the whole thing off again.
  With REFRESH=0 variable RUNAYADN should let the while..do exit back to the command prompt.

I can only get the 2 options to either refresh or exit - not behaving as intended.

Did I mention I'm a Linux noob yet?

The files:


----------
ayadn_run.sh (commented!) follows:
----------

#!/bin/bash
# ~/Documents/ayadn_run.sh

clear
RUNAYADN=1
while [ "$RUNAYADN" = 1 ]
  do
    mux ayadn
    RUNAYADN=1
# RUNAYADN=1 substituted for the next line
# I can't get the REFRESH variable to 'export' from ayadn_shell
#    RUNAYADN=$REFRESH
  done
echo "Press a key"
read KEYPRESS
echo "Done."
exit


----------
ayadn.yml follows:
----------

# ~/.tmuxinator/ayadn.yml

# A Tmuxinator layout for the Ayadn App.net command line client

# Prerequisites:
# 1. Ruby and Tmux and Tmuxinator must be installed. It's non-trivial but brings its own, peculiar, rewards.
# 2. An understanding that I'm new to Linux - I'm pretty sure this code won't break anything but be careful if you wish to modify it.
# 3. An understanding that, because I'm new to Linux I've created about 13 documents thus far. All in ~/Documents - easy.

Oops - I could have added files!
Anyway, I suspect that 'export REFRESH=1' and 'export REFRESH=0' are not exporting out of the killed Tmux session to the shell script calling it. Maybe I need to get into Tmux rather than taking the easy option?
